There is supposed to be a captcha right here. If you don't see it, that's weird, and you'll be prevented from signing up for an account. If this is happening to you, please contact support and we'll make sure you get an account.

We're all for progressive enhancement, but CodePen is a bit unique in that it's all about writing and showing front end code, including JavaScript. It's required to use most of the features of CodePen.

Close this, use anyway.
